ATTACHMENT FOR LINOTYPE-MACHINES.

Specification of Letters Patent.

Patented'June 13, 1916.

T 0 all whom it may concern:

Be it known that I, GEORGE R. WAGNER, a citizen of the United States of America and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Attachments for Linotype-Machines, of which the following is a specification, reference being bad to the accompanying drawings, forming a part thereof.

My invention relates to the manufacture of metal wedges such as are used by printers and are commonly known as quoins.

Metal wedges or quoins are employed in pairs by printers for clamping columns of type on galleys. These wedges are used in large quantities and have hitherto been produced at considerable expense by pourin molten metalinto molds, by hand, an finishing the wedge surfaces by filing, many of the wedges being so imperfectthat they could not be used.

It has been my aim to provide a mold attachment for linotype or like type-setting machines, by means of which perfectly finished quoins may be readily and quickly made at small cost.

Another'object of my invention is to provide a simple and improved mold for typesetting machines, particularly adapted for relatively heavy work, embodying simple and efiective means for preventing the casting from being drawn back while it is being sheared off by the cutter.

Other objects .and advantages of my invention will be set forth hereinafter, and in. order that my invention may be thoroughly understood, I will now describe the same in the following specification and then point out the novel features thereof in appended claims. 1

Referring to the drawings: Figure 1 is a partial elevation of a mold wheel to which my invention is applied. Fig. 2 is a sectional elevation through the mold wheel showing the mouth of the melting pot and the elevator on oppositc'sides of the wheel in position for casting. An elevation of a portion of the matrix is shown in Fig. 3. Fig. 4 is a partial elevation of the mold drawn to'a lal'ger scale and looking toward the matrix. A perspective View of one of thequoins is shown in Fig. 5.

Wh eI have lllustrated my mventionas applied to the manufacture of ,uoins, it is not limited imthis field of use ulness and may be employed for heeyy slugs of various kinds. I

10 represents a mold wheel, 11 the mouth and throatof a linotype-pot, and 12 an elevator, all of a well known design.

The mold of my invention-is shown at 15, and has a flange 16 so that it is adapted to fit into the mold wheel as shown in Fig. 2.

"It is rcmovably secured in place byscrews A matrix 21 which is adapted to be mounted on the elevator 12 in a well known man ner, has a core projection 22 which extends into the slot 18 in the mold and serves to lighten the quoins by materially reducing the volume of the die, comprising the mold 1 and matrix, into which the molten metal is forced from the pot.

Both the mold and the matrix are detachably secured in position and may be easily and quickly mounted in a linotype machine of well known construction. When so mounted, quoins may be quickly produced in the type-setting machine by the usual type-setting process.

Quoins produced in this manner l}ave the advantage of being substantiallyper 'ect and finished as they come from the machine and consequently the labor of filing or finishing as well as the loss due to imperfect castings, is avoided.

Assuming that the parts occupy the positions in which they are shown in Fig. 2, if the plunger of the linotype pot is then actuated to force molten metal into the die, a quoin will be cast as shown in the same figure. The strip or bar 20 is placed in a position to securely hold the quoin while the metal is being sheared oil", in a well known manner, by the cutter. It nevertheless does not in any way interfere with the operation of the cutter nor with the ready removal of w the quoin from the mold.

clearly shown .in Fig. 2, it is offset from,

Furthermore, as

and substantially parallel to, the mouth opening of the melting pot so that it does not obstruct the opening or interfere with 'the free movement of molten metal into the die.

Modifications may obviously be effected within the spirit and scope of my invention, and I intend that only such limitations be imposed as 'are indicated in the appended claims.

What I claim is:

1. A quoin molding machine comprising a support, a mold block secured, thereto, the thickness of the mold block being the same as the desired height of the quoin and being constructed with a slot extending through it, shaped to produce the tapering walls of the quoin, a. melting pot having a narrow discharge passage opening into said slot, a

member, a core member secured thereto having a core projection of less area than that of the tapering slot of the mold and a strip extending through the slot to prevent the drawing out of the casting when the support is actuated.

2. A quoin molding machine comprising 1,1ae,esa

a support, a mold block removably secured thereto, the thickness of the mold block being the same as the desired height of the quoin and being constructed with a slot extending through it, shaped to produce the tapering walls of the quoin, a melting pot having a narrow discharge passage opening into said slot on one side of the block, a member, a core member removabl secured to said member having a core prO ection of less area than that of the tapering slot of the mold adapted to extend into the slot from the opposite side of the block, and a strip affixed in the mold block at the surface which is adjacent to the mouth of the melting pot and extending through the mold slot substantially parallel to the mouth of the pot and oilset therefrom to leave the mouth opening unobstructed and to prevent the drawing out of the casting when the support is actuated.

In testimony whereof I have hereunto set my hand this 12th day of December 1914, in ti. pres so of two subscribin witnesses.
